+- update to version 3.66.0:
+  * This release improves validation of the alphabet argument to the
+    text() strategy. The following misuses are now deprecated, and
+    will be an error in a future version:
+    + passing an unordered collection (such as set('abc')), which
+      violates invariants about shrinking and reproducibility
+    + passing an alphabet sequence with elements that are not strings
+    + passing an alphabet sequence with elements that are not of
+      length one, which violates any size constraints that may apply
+
